IMPROVEMENT lN HOLLOW HAND-CUTTERS FOR LEATHER, &c.

Specification forming part of Letters Patent No. 147,047, dated February3, 1874; application filed December 13, 1873.

To all whom it may concern:

Be it known that I, ABEDNEGO DEwEs, of Hudson City, in the county ofHudson and State of New Jersey, have invented a new and usefulImprovement in Hollow Hand-Cutters for Leather, Cloth, Paper, 860., ofwhich the fol- 1 lowing is a specification:

My improvement in hollow cutters, for cutting out shapes from leather,cloth, paper, 850., by hand, consists of detachable handles for saidcutters, said handles being adapted for several different sizes, theobject of which is to save the cost of so many handles. Instead of ahandle for each cutter, I propose to have only one handle to three orfour sizes of cutters, and shift it from. one to the other as I wish touse them.

The fastening device will be simple, so as to make but little labor andloss of time in making the changes; but the changes have not to be madefrequently, for large quantities of shapes may be cut by each cutterwithout changing.

The handles usually cost nearly as much as the cutter itself, so that,as my detachable handle only costs a trifle more than the ordinaryhandle, a considerable saving will be effected to every set of cuttersby my plan.

I also propose to construct my handle so that the force of the malletwill be delivered on the ends of the cutters as well as on themiddle-where it is only delivered in the ordinary hand-cut-tersso that Iavoid the springing of the cutters at the middle, common to the cuttersnow in use, by which I can do the work better and more rapidly.

Figure 1 is a sectional elevation of a handcutter with a handledetachably connected to it. Fig. 2 is a plan of the bottom of Fig. 1;and Fig. 3 is a side elevation of a wrench to be used in fastening andunfastening the devices which I have represented in this example forsecuring the handle to the cutter.

Similar letters of reference indicate corresponding parts. i

A represents the cutter, which is in the or dinary form, and, withoutthe handle, is like those used for cutting in a press by power. B is thehandle, which, in this example, has four strong arms, 0, branchinghorizontally from the lower end, to extend over and project beyond thetop of the cutter in its long and short axes. D represents a couple ofstrong spring bars or bolts for fastening the handle to the cutter. Theyare slotted at one end, and meet together at the clamping-bolt E, whichpasses through the slots, and screws into the center of the bottom ofthe handle, while the other ends slide out through the ends of thecutter, which have a hole therefor, as clearly shown in the drawing.

To detach the handle, the screw-bolt is loosened a little by the wrench,and the fasteningbolts are withdrawn from the holes in the cutter. Themode of fastening the handle on is obvious.

It will be seen that the strong arms 0, which. projects over the ends ofthe cutter, will prevent it from springing down at the middle under theinfluence of the blow of the mallet, as the common hand-cutters do, inwhich the handle is attached to the middle of the cutter.

The arms 0 will extend as far beyond the cutter as is necessary to makethem long enough for the largest cutter for which the handle isintended.

Having thus described my invention, I claim as new and desire to secureby Letters Pat ent- In combination with a cutter, A, the detachablehandle B, provided with arms 0, secured by means of a screw-bolt, E, tothe movable slotted springs D D, substantially as herein shown anddescribed.
